Summary
Ammonium polyacryloyldimethyl taurate (APT) enhances perovskite solar cell (PSC) stability and efficiency by improving film quality and passivating defects. This novel surfactant also reduces lead leakage, addressing key challenges for commercialization.
Area of Science:
- Materials Science
- Renewable Energy
- Chemical Engineering
Background:
- Perovskite solar cells (PSCs) offer high efficiency and low cost but suffer from instability and lead content.
- Commercialization of PSCs is limited by perovskite film quality, degradation, and environmental concerns.
- Existing solutions often fail to address multiple challenges simultaneously.
Purpose of the Study:
- To introduce ammonium polyacryloyldimethyl taurate (APT) as a multifunctional additive for PSCs.
- To investigate APT's role in improving perovskite film quality and device performance.
- To assess APT's impact on environmental stability and lead leakage mitigation.
Main Methods:
- Utilizing the amphiphilic nature of APT for self-assembly in precursor solutions.
- Employing APT to regulate interfacial tension and template perovskite crystal growth.
- Characterizing perovskite films for crystallinity, grain size, and defect passivation.
- Evaluating device performance (PCE) and environmental stability under various conditions.
- Assessing lead ion coordination and leakage.
Main Results:
- APT addition resulted in perovskite films with enhanced crystallinity, uniform grains (>2 µm), and fewer defects.
- Power conversion efficiency (PCE) increased from 23.37% to 25.17% due to defect passivation and reduced non-radiative recombination.
- APT imparted significant moisture resistance, enhancing environmental stability.
- APT effectively coordinated with lead ions, minimizing lead leakage risks.
Conclusions:
- APT is a versatile additive for simultaneously enhancing perovskite film quality, device efficiency, and stability.
- The multifunctional nature of APT addresses critical challenges in PSC technology.
- APT shows promise for developing more stable, efficient, and eco-compatible perovskite solar cells.
